DeSean Jackson, plz (edit: cleared waivers)

How does it work, if he is claimed on waivers do you pay his currently salary? But if he clears them, you can sign him to a new contract?

Our only hope is he’s paid more than ppl would like to pay, and he gets to go anywhere. And chooses us because we have the best offensive mind still looking for a receiver.
When you make a waiver claim you are claiming the current contract. If he clears waivers then he is a free agent and can be signed to whatever he agrees to.
